Reaction Steps

To a stirred mixture of 74.2 g (0.455 mole) ##STR16## ethylphosphonothioic acid dichloride in 400 mls benzene, 30.1 g (0.5 mole) isopropyl alcohol was added. To that mixture 50.6 g (0.5 mole) triethylamine was added at a dropwise rate overnight. The mixture was then warmed for about 1 hour. The mixture was filtered by gravity. Most of the solvent (benzene) was stripped off under reduced pressure and heat to give ethyl-O-isopropylphosphonothioic chloride ##STR17##
